It is the answer because the opposite interior angles should equal the exterior angle when you add them up and 34 plus 53 equals 87.

Answer:

Area: 50.24 square units

Center: 4,2

Step-by-step explanation:

The midpoint can be found using [tex]\frac{a+b}{2}[/tex] for both x and y

(8+0)/2=4

(2+2)/2

We have our center, so let's move on.

The area of a circle is the radius squared multiplied by pi.

Since the diameter is 8, the radius is 4.

4*4=16

Hey there!

First, let's solve this problem.

We have

5×1/4

First, let's write 5 as a fraction:

[tex]\bold{\displaystyle\frac{5}{1} }[/tex]

Now, divide:

[tex]\bold{\displaystyle\frac{5}{1} :\frac{1}4}[/tex]

Flop the second fraction over:

[tex]\bold{\displaystyle\frac{5}{1} :\frac{4}{1} }[/tex]

And now multiply the first fraction times the second one:

[tex]\bold{20}[/tex]

Now, how to solve fraction problems using reciprocals?

5 divided by 1/4 is 20.

A mathematical arithmetic operation is a multiplication. Moreover, it is the practice of repeatedly adding the same expression kinds.

Example: 2 + 3 means that 2 is multiplied by 3 or that 3 is multiplied by 2 times.

Given:

A phrase: 5 divided by 1/4.

To solve a fraction division problem using reciprocals:

Let n be the required value of the quotient.

n = 5 ÷ 1/4

n = [tex]\frac{5}{1/4}[/tex]

To convert the division to multiplication:

Reverse the number in the denominator,

n = 5 x 4/1

n = 20

Therefore, the value of the quotient is 20.

Answer:Volume of cylinder V= bh= 78 cm^3,

where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3Upvote•0Downvote Add comment

Answer :D

The volume of the cone is [tex]26^{}[/tex] [tex]cm^{3}[/tex]

Question explanation:

Okay, so, we know that.

The volume of a cylinder is equal to:

There are 3 full quarts of paint does the crew need to buy in order to paint the entire platform

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

This figure represents a platform in a park. The grounds crew needs to paint it yellow.

And, One quart of paint will cover 100 square feet.

Now, Total are of the platform in a park is,

⇒ 2 (7 × 4) + 2 (8 × 8) + 2 (8 × 2) + 2 (7 × 2)

⇒ 56 + 128 + 32 + 28

⇒ 244 square feet.

Here, One quart of paint will cover 100 square feet.

Hence, For 244 square feet area;

Amount of paint = 244 / 100

                         = 2.44

                         ≈ 3

Thus, There are 3 full quarts of paint does the crew need to buy in order to paint the entire platform

The amount that each person would get after the sub is divided in 5 people equally is lesser than the amount of sub that they were getting when there were 4 people.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

Firstly the sub was divided in 4 parts,

and when 5 people came, so it was  decided to share the sub in 5 equal parts.

The more we increase the number in which the considered thing (here sub) is to be divided, the lesser each part would be.

Let the sub is measured as 'a' units.

Each person would get: [tex]\dfrac{a}{4}[/tex]

Each person would get: [tex]\dfrac{a}{5}[/tex]

We know that:

[tex]4 < 5[/tex]

Multiply both the sides by 'a', assuming 'a' is positive, we get:
[tex]4a < 5a[/tex]

Divide both the sides by 20:

[tex]\dfrac{4a}{20} < \dfrac{5a}{20}\\\\\dfrac{a}{5} < \dfrac{a}{4}[/tex]

Thus, the amount that each person would get after the sub is divided in 5 people equally is lesser than the amount of sub that they were getting when there were 4 people.

Step-by-step explanation:

Answer:

Step-by-step explanation:

You can use calculus to derive the equation for the volume of a cone.

if we take an circle at the tip of the cone the radius is 0 but what we want to do is integrate along the x axis from 0 up to the height of the cone H.

So, the equation becomes

[tex]\int\limits^H_0 {\pi r^{2} } \, dx[/tex]

r is related to x by the formula for a line;  r = m*x+b

m is the rise over the run which is given by the maximum height H divided by the maximum radius R.  So m = H/R and the intercept b = 0

now we have a formula for r in terms of x and with a little variable manipulation we can get a formula for x in terms of r

r = (R/H)*x

If we replace r by this formula in our integral we get:

[tex]\int\limits^H_0 {\pi ((R/H)*x)^{2} } \, dx[/tex]

since [tex]\pi[/tex], R, and H are constants we can move them outside the integral:

[tex]\pi (R^{2} /H^{2} )*\int\limits^H_0 {x^{2} } \, dx[/tex]

the integral is easy.  It is [tex]\frac{x^{3}}{3}\left \{{{x=H}\atop{x=0}} \right.[/tex] which is equal to [tex]H^{3} /3[/tex]

substituting back into the original formula we get the equation for the volume of a cone.
V = [tex](\pi R^{2}H)/3[/tex]

Use this formula with the values given in the question to solve for R.

183.17 = [tex]\pi[/tex][tex]R^{2}[/tex]*7/3

rearranging we get

[tex]\sqrt{183.17*3/(7\pi ) }[/tex] = R

R ≅ 5
